実験手順

0.22 g (0.55 mmol) of 1-[2-(benzylthio)-8-oxo-5,6,7,8-tetrahydroquinazolin-7-yl]-2-phenylethane-1,2-dione were dissolved in 6 mL of ethanol and 0.03 g (0.66 mmol) of methyl hydrazine were added. The reaction mixture was maintained under stirring at refluxing temperature for 5 hours. After that time the solvent was removed under reduced pressure, the residue redissolved with dichloromethane and washed with water. The organic layer was dried over Na2SO4 and concentrated, giving 0.16 g of the title compound (70% yield).
